Launch HN: Lang (YC S19) – Internationalization Built for Devs

Hey HN! We’re Eric, Peter, and Abhi, founders of Lang ( https://www.langapi.co ). We help developers quickly translate their apps into foreign languages by combining internationalization SDKs with a command-line interface that integrates directly with human translators. Previously, we all worked on building internationalization and localization tooling for companies. In our experience, companies don’t think about translation until too late, and the tech debt builds up very fast. It’s a nightmare to receive a task that says “translate app into Spanish.” Choosing the right open-source framework, refactoring the entire codebase, and integrating with human translators is a massive effort. As engineers, we wanted to work on features - not putting every string in our codebase into a translations.json file. In our months of internationalization work, we couldn’t find a good all-in-one toolkit. So we built Lang. Like other internationalization libraries, Lang gives you a tr() functio
